WebAug 1, 2024 · As is well-known, the quasi-phase matching (QPM) technique could effectively refrain from the limitation of the birefringence. QPM technique could offset the dispersion-induced phase mismatch by a reciprocal lattice vector, resulting from a periodic structure with space-dependent second-order nonlinear coefficients [39], [40], [41], [42]. WebJan 18, 2024 · Quasi-phase matching (QPM) is a technique in nonlinear optics for achieving efficient energy exchange among optical waves at different frequencies, by spatially modulating the quadratic nonlinearity (χ (2)) of the medium.To realize the full potential of QPM, 3D spatial modulation of χ (2) is required. This has become experimentally feasible … WebJun 16, 2007 · We analyze quasi-phase-matched (QPM) conversion efficiency of the five possible types of periodic two-dimensional nonlinear structures: Hexagonal, square, rectangular, centered-rectangular, and oblique.
